Innocent was a canon lawyer of some eminence. His small work De exceptionibus was probably written before he became pope; but the Apparatus in quinque libros decretalium, which displays both practical sense and a remarkable mastery of the available materials, was written at Lyons immediately after the council. His Apologeticus, a defence of the papal claims against the Empire, written—as is supposed—in refutation of Piero della Vigna’s argument in favour of the independence of the Empire, has been lost. Innocent was also a notable patron of learning, he encouraged Alexander of Hales to write his Summa universae theologiae, did much for the universities, notably the Sorbonne, and founded law schools at Rome and Piacenza.
Innocent’s letters, the chief source for his life, are collected by E. Berger in Les Registres d’Innocent IV (3 vols., Paris, 1884-1887). For English readers the account in Milman’s Latin Christianity, vol. vi. (3rd ed., 1864) is still useful. Full references will be found in Herzog-Hauck, Realencyklopädie, vol. ix. (1901).

Innocent V. (Pierre de Champagni or de Tarentaise), pope from the 21st of January to the 22nd of June 1276, was born about 1225 in Savoy and entered the Dominican order at an early age. He studied theology under Thomas Aquinas, Albertus Magnus and Bonaventura, and in 1262 was elected provincial of his order in France. He was made archbishop of Lyons in 1271; cardinal-bishop of Ostia and Velletri, and grand penitentiary in 1275; and, partly through the influence of Charles of Anjou, was elected to succeed Gregory X. As pope he established peace between the republics of Lucca and Pisa, and confirmed Charles of Anjou in his office of imperial vicar of Tuscany. He was seeking to carry out the Lyons agreement with the Eastern Church when he died. His successor was Adrian V. Innocent V., before he became pope, prepared, in conjunction with Albertus Magnus and Thomas Aquinas, a rule of studies for his order, which was accepted in June 1259. He was the author of several works in philosophy, theology and canon law, including commentaries on the Scriptures and on the Sentences of Peter Lombard, and is sometimes referred to as famosissimus doctor. He preached the funeral sermon at Lyons over St Bonaventura. His bulls are in the Turin collection (1859).

Innocent VI. (Étienne Aubert), pope from the 18th of December 1352 to the 12th of September 1362, was born at Mons in Limousin. He became professor of civil law at Toulouse and subsequently chief judge of the city. Having taken orders, he was raised to the see of Noyon and translated in 1340 to that of Clermont. In 1342 he was made cardinal-priest of Sti Giovanni e Paolo, and ten years later cardinal-bishop of Ostia and Velletri, grand penitentiary, and administrator of the bishopric of Avignon. On the death of Clement VI., the cardinals made a solemn agreement imposing obligations, mainly in favour of the college as a whole, on whichever of their number should be elected pope. Aubert was one of the minority who signed the agreement with the reservation that in so doing he would not violate any law, and was elected pope on this understanding; not long after his accession he declared the agreement null and void, as infringing the divinely-bestowed power of the papacy. Innocent was one of the best Avignon popes and filled with reforming zeal; he revoked the reservations and commendations of his predecessor and prohibited pluralities; urged upon the higher clergy the duty of residence in their sees, and diminished the luxury of the papal court. Largely through the influence of Petrarch, whom he called to Avignon, he released Cola di Rienzo, who had been sent a prisoner in August 1352 from Prague to Avignon, and used the latter to assist Cardinal Albornoz, vicar-general of the States of the Church, in tranquillizing Italy and restoring the papal power at Rome. Innocent caused Charles IV. to be crowned emperor at Rome in 1355, but protested against the famous “Golden Bull” of the following year, which prohibited papal interference in German royal elections. He renewed the ban against Peter the Cruel of Castile, and interfered in vain against Peter IV. of Aragon. He made peace between Venice and Genoa, and in 1360 arranged the treaty of Bretigny between France and England. In the last years of his pontificate he was busied with preparations for a crusade and for the reunion of Christendom, and sent to Constantinople the celebrated Carmelite monk, Peter Thomas, to negotiate with the claimants to the Greek throne. He instituted in 1354 the festival of the Holy Lance. Innocent was a strong and earnest man of monastic temperament, but not altogether free from nepotism. He was succeeded by Urban V.
